The Tooth Fairy and the FBI

Our Tooth Fairy has a bad memory. She often forgets to leave the money under the pillow the first night. Once, last year, she brought the money the next morning, after I called and demanded better service. The girl was suspicious of this and took matters into her own hands. The following is a letter she wrote to the FBI: (spelling is actual)
Dear FBI,
Here's a dallor for you. We would like you to check for fingerprints. Send us a list of people and send dallor back!
From,
boy and girl

The following is the response from the "FBI" to the girl's letter: (which arrived one hour after her l;etter went out on a Sunday)
Dear Ms. X,
We received your dollar bill from the Tooth Fairy. We processed the bill in our very expensive crime lab. We even had our highly paid scientists look at it with magnifying glasses and some other scientific machines, some of them making noises like bing, whoop, and good golly miss molly.
Here's what we found. The dollar bill had fingerprints all over it - YOURS! Thank you for wasting our time and tying up highly paid scienists and expensive machines that make noises like clang, heehaw, and wally gobbler.
We do see a promising future for you in law enforcement. Please apply for a job with the FBI when you are old enough.
